Download and install R prior to building PL/R. - R must have been built with the --enable-R-shlib option when it was configured, in order for the libR shared object library to be available. - R_HOME must be defined in the environment of the user under which PostgreSQL is started, before the postmaster is started. Otherwise PL/R will refuse to load. Installation: See http://www.joeconway.com/plr/doc/plr-install.html for the most up-to-date instructions. Place these files in a directory called 'plr' under 'contrib' in the PostgreSQL source tree. E.g. place the tarred source file in '/path/to/pg_source/contrib' and run: tar -xzf plr-x.y.z-alpha.tar.gz Then run: cd /path/to/pg_source/contrib/plr make make install make installcheck This is usually best done logged in as the PostgreSQL superuser (defaults to postgres), except root privileges may be needed for "make install". You can use plr.sql to create the functions in your database of choice, e.g. psql mydatabase < plr.sql Documentation: See the following files: doc/plr.sgml - PL/R documentation source doc/*.html - Preprocessed html version of the documentation ====================================================================== -- Joe Conway
